I don't think this is a spoiler since its regarding the end quest reward.
You get 3 items one of which is a pack with HK gear inside. Your HK comes geared, so I looked at it and thought well maybe its appearance or something along those lines, lets look inside. Its the same gear and its bound. On top of that I used cartel coins to unlock it on my other main, guess what, he comes naked.
Its not a huge deal I'll spend some time gathering gear for the naked one. I just wanted to put that warning out there. Don't open that pack when you get your first HK send it to the next character you unlock it on.
